Specification of Letters Patent. I

Patented Ma 19, 191 4.

Application filed August 15, 1913. Serial No. 784,924.

residing at Gratz, in the Empire of Austria- 2 and 3 show the me'chanism'in two different positions. Fig. 4, shows the kinematicco- Hungary, have invented certain new and useful Improvements in Type-VVriters, of which the following is a specification, reference being hadtherein to the accompanying drawing.

As is well known the inking ribbon of typeWrit-ing machines is made to unwind from one'spool upon the other by striking the operating keys, and it is necessary to provide means for reversing the winding movement when thB '1'lbbO1l has been completely unwoundfrom one of the spools. In machines of the kind in which this reversing movement does not take place automatically, it must be produced by the alternate opposite movements of a reversing member, and by releasing and readjusting fixing devices, and the necessity for attending to these operations, distracts the operators attention from writing.

My device is characterized by the fact'that the reversing movements are obtained from the reciprocation of a reversinglever which is alternately actuated by two crank pins of a resilient key, by the intermediary of two members, rigidly connected with each other and with a trip arm-arranged in their angle; the rigid system composed of the two members and the trip arm being rockably mounted on the reversing lever, within alimited extent, and being directly actuated by the crank pins of said key which bear alternately against thefree ends of the tigb members.

Another feature of the invention resides in the fact that for the purpose of insuring the movement into its two end positions and retaining it therein, the reversing lever is providediupon its upper end with two converging striking surfaces, in each of which there is a notch; a roller, or a knife edge, preferably mounted on the end of a resilient lever, acts against'these striking surfaces.

The invention is fully illustrated in the accompanying drawing, in which:

Figure 1, shows the operating mechanism in yertical longitudinal section of themachine, paralleljwith the inking ribbon. Figs.

operation of the constructional elements diagrammatically; Fig? 5, is a section on the line AA, in Fig.1 viewed from the right.

The inking ribbon it is caused to be unwound from the spool t and to be wound upon the other spool s; the alternating movement of the spools t and s, is obtained from a shaft n, adjustable in the direction of its length, and which, by means of the operating pawl m, actuated at each de ression of a key, rotates, to the extent 0 one tooth, the ratchet wheel 0, keyed upon the shaft 91.. Two bevelpinions 20, 21, are keyed upon this shaft n, and, by the longitudinal movement of the shaft 02., these pinions are caused to mesh with the driving shaft a, of the spool t, or with the driving shaft 6 of the spools. The longitudinal movement of the shaft n which is required for reversing the movement of the ribbon, is effected-by the lever q, rockable upon the;

.bolt f: the lower end of this lever g carriesa claw d, which loosely engages uponthe edge of a disk j, fixed on the shaft'n.

The present invention has for'its object to insure the reciprocatory movement of this operating lever g, by the actuation of .a resilient, or spring operated keyp, always tak-.

ing place in the same direction, thereby shifting this lever with certainty into its end positions and securing it therein. With this object in view an anchor-like member '0, is pivoted onthe lower arm of the lever g at the point 1; (see Fig. 4). This member 1;; consists of two rigidly connected membens,."2 and 4, set at a-certain angle one to the I other, and rigidly connected with an arm '3, located in the space between the mom bers 2 and4, and carrying a trip weight'k.

Stop pins 5, 5, arranged-upon the members i 2, and 4:, orupon the trip armB, liniit the extent of oscillation of the entire system constituted by the rigidly connected parts 2, 3 and .4, relatively to the operating lever g'.

The free ends of the two members. 2 and 4,

have n'otched striking surfaces 6 and 8,

against which the crank pins 7 and9, of the spring operated key lever, act.

One of the positions of the] system indicated by the Figs. 2, 3, 4, corr'esponding to the two operative positions of the lever g,.i's shown in solid lines and the second position, in broken lines; (See Fig. 4.) the'po- ,s ition shown \in solid lines the crank pin 7, ofthe 'key 39 rotatable about the shaft 10, rests upon the'vsurface 6 of the member 2; if the key?) is depressed the pin.

7 presses the member. 2 downward toward the right and thispart'bccoming operative in the direction fndicated'by the arrow 11, imparts a right hand movement to the pivot point '1, causing the lever q to osc'illatein the direction indicated by't-he arrow 11. As the pin 7 remains in engagement with the surface 6 of the membe'rQ, this rotation of the lever lasts until the end of the stroke of the key p, or until the lever q hasreached the end position 9 shown in broken lines diagrammatically, in Fig. 4. By this means however, the system 2, 3, a, has been shifted beyond its middle position bygthe movement of its pivot point 1, to 1". When the key lever has been released it springs upward, and therefore also releases the system, 2, 3',

4, and the latter under the influence of theweighted trip arm 3, rocks into its lowest position, determined by the striking of the right hand stop pin 5, against the lever 1..

This position is represented in 3, and

diagrammatically illustrated by the lines 2,

3, l, in Fig. 4. By this rocking movement however, the striking surface 8, ,of the member l, has come beneath the second crank pin 9 of the key lever 39, so that when the key is again depressed the lever g is automatically returned to-the position shown in Fig. 1,-

that is to say, the position diagrammatically represented in solid lines, Fig. i, by the operation of the right hand member 4. From this it'will be noted that by the successive depressions of the key 2, the operating lever is first oscillated to theright, and then to the left, thereby reversing the movements of the inking ribbon. In order that the operating lever, "may be conducted to its endposition, with certainty, and retained in this position, upon its upper end, two converging striking surfaces 12, 12, ending in notches 13, 13, are provided, and against these surfaces a weighted roller 3 preferably mounted on the end of a resilient arm 1w, operates so that the action of the roller pressure ends only when the roller has entered one of the notches 13.

In order to assist the action of the trip weight- 3, two converging striking surfaces '14, 14, are provided at the end of the trip arm 3 against these surfaces a wedge shaped knife edge u, on the end of a spring controlled lever a, operates, and owing to the movement of the key lever. this knife edge u is carried beyond the apex, and then exerts a tangential, pressure upon the striking surfaces over which it has traveled, thus as- 'sisting a, the turning'movement of the trip weight and thereby insuring the trip movement, even if the carrier is in bad condition.

Havin now described my invention and the manner in which it is to be used, what I 1. Ina type writing machine having ribbon wheels and mechanism to wind the ribbonalternately from one wheel to the other, a transverse operating shaft, a, weighted arm, two rigidly connected members having recessed upper faces fixed on said weighted arm a spring controlled key having pins thereon to engage saidweighted arm and depress said rigid members, and means on said arm .to engage a d1sk on the inner end of said transverse shaft.

= ,2. In a typewriting machine a horizontal rocking member loosely engaging a disk on,

said horizontal shaft, as described.

in witness whereof I have hereunto setmy hand in presence of two witnesses.
